Answer:
3
Step-by-step explanation:
Let's put that number as x.
It says that one minus 4 times x is 11.
So the equation is 4x - 1 = 11.
Add one on both sides to get 4x = 12.
Divide by four on both sides to get x = 3.
Since x is what we are looking for, the answer is 3!

O A. As the value of x increases, the value
B. The domain of the function is (-2, 00).
OC. The function has a y-intercept at (0,-2).
OD. The function is increasing.
The correct answer is [a]. As value of the x increases the value
According to this function, the value of f(x) grows closer to a constant as the value of x rises.
What is the purpose?A relationship between a group of the inputs and one output each is referred to as a function.
The function specified is;
[tex]f(x)= (\frac{1}{5})^{x}-2[/tex]
According to this function, value of f(x) travels in the direction of a constant as the value of x rises.
(-2,00) is function's domain.
The y-intercept of function is at (0,-2).
The performance is the deteriorating.
As a result, statement that this function advances toward a constant value as x rises is accurate.

(Lesson 5: Equations and Their Graph Discussion)
In general, how can a graph help us find solutions to two-variable equations?
A graph can help us find solutions to two-variable equations through the point of intersection.
How to illustrate the information?The appropriate steps will be:
Draw a graph for each side, or component, of the equation and check to see where the curves intersect, or are equal, to solve an equation graphically.
The answers to the equation are the x values of these places.
Plotting the graph of each equation allows us to clearly understand the solution. The point of intersection of the two lines is where the solution, which is an ordered pair that satisfies both equations, occurs on both lines.
Therefore, a graph can help us find solutions to two-variable equations through the point of intersection.

To score an A, the score on the third test should be 79.
To lose your B grade, you have to score less than 49 on the third test.
What should be the score on the third test?The average of a set of numbers is the sum of the numbers divided by the total numbers.
Average = sum of scores / total numbers
90 = (86 + 85 + x) / 3
90 = (191 + x ) / 3
Where x is the score on the third test
In order to determine the value of x, take the following steps:
Multiply both sides of the above equation by 3
90 x 3 = 191 + x
270 = 191 + x
Subtract both sides of the equation by 191
270 - 191 = x
x = 79
The equation that represents the score that would make you lose the B grade is:
80 = (86 + 85 + x) / 3
80 = (191 + x) / 3
In order to determine the value of x, take the following steps:
Multiply both sides of the equation by 3
80 x 3 = (191 + x)
240 = 191 + x
Subtract 191 from both sides of the equation:
x = 240 - 191
x = 49
To lose your B grade, you have to score less than 49 on the third test.

What is the law of detachment in geometry. ELI5 please! Thank you! Oh P.S. ELI5 means Explain like I'm 5
In geometry "rule of detachment," states that if P leads to Q and P is true, then Q must also be true
What is geometry?The area of mathematics known as geometry is concerned with the dimensions, sizes, forms, and angles of a wide range of everyday objects. The terms "geometry" and "metron" are derived from Ancient Greek words that mean "measuring" and "Earth," respectively.
The most widely applied deductive reasoning premise is the Law of Detachment. This law states that the conclusion is valid whenever a conditional statement and its hypothesis are true. The conclusion can therefore be "separated" from the conditional.
According to the geometry's "rule of detachment," if P leads to Q and P is true, then Q must also be true. Despite the fact that it is stated in a different format, this is still a conditional statement.

Is 0.2525252525252525 a rational or irrational
Answer: Yes
Step-by-step explanation:
A repeating decimal can be a rational number.
Rational
Step-by-step explanation:Rational and irrational numbers are 2 of the broadest categories within real numbers.
Writing the Number as a Fraction
Rational numbers are defined as numbers that can be written as simple fractions. Simple fractions have integers for the numerator and denominator. This means neither the numerator nor denominator is a fraction or decimal. The number above is 0.25 repeated. When 2 digits are repeated you can place that number over 99 to create an equivalent fraction.
0.2525252525252525 = [tex]\displaystyle \frac{25}{99}[/tex]Since this number can be written as a fraction, it must be a rational number.
Bar Notation
Additionally, repeated decimals are always rational. In the example above, the digits .25 are repeated. If you don't want to write it as a fraction, you can use bar notation. Bar notation helps to shorten repeated decimals and show that they are rational. In this notation, you place a bar over the digits that are repeated.

Complete the square to determine if the equation is a circle, quadratic (parabola) or other. Show all work and graph the circles and quadratics on a grid.
The equation of the ellipse, circle, and parabola will be written as (x + 9)² / 4 + (y - 1)² / 16 = 1, (x + 4)² + (y - 3)² = 40, and y = - (x + 3)²/ 4 + 1, respectively.
How to draw the graph of the function?Equation A is transformed as,
16x² + 4y² + 96x - 8y + 84 = 0
16(x² + 6x + 9 - 9) + 4(y² - y + 1 - 1) + 84 = 0
16(x + 9) - 144 + 4(y - 1)² - 4 + 84 = 0
16(x + 9)² + 4(y - 1)² = 64
(x + 9)² / 4 + (y - 1)² / 16 = 1
This is the equation of the ellipse.
Equation B is transformed as,
x² + y² + 8x - 6y - 15 = 0
x² + 8x + 16 + y² - 6y + 9 - 15 = 16 + 9
(x + 4)² + (y - 3)² = 40
This is the equation of the circle.
Equation C is transformed as,
x² + 6x + 4y + 5 = 0
x² + 6x + 9 - 9 + 4y + 5 = 0
y = - (x + 3)²/ 4 + 1

Solve. Check for extraneous solutions. (2 x+3)¹/₂-7=0
No extraneous solution to the equation.
The equation is
[tex](2x + 3)^{1/2}[/tex] - 7 = 0
To find whether the equation has an extraneous solution, first we have to find the value of x.
[tex](2x + 3)^{1/2}[/tex] = 7
Squaring both sides, we get
2x + 3 = 49
2x = 46
x = 23
Now put the value of x in the equation,
[tex](2 * 23 + 3)^{1/2}[/tex] - 7 = 0
[tex](46 + 3)^{1/2}[/tex] - 7 = 0
[tex]49^{1/2}[/tex] - 7 = 0
7 - 7 = 0
0=0
Therefore we get that there is no extraneous solution to the equation, x= 23 is the solution of the equation.

Step-by-step explanation:
For each function, identify the transformation from the parent function y=b x . y=5 x+3
Transformation of y= b*x into y = 5x + 3 will take place by vertical dilation by a scale factor of 5 and vertical translation of 3 units.
A parent function is the simplest form of a particular family of functions. A family of operations is a group of tasks with the same highest degree and therefore the same graph shape.
Function transformations "move" "resize" or "mirror" the graph of the parent function.
Mathematically speaking, the transformation of the function y = f(x) is usually y = a f(b(x + c)) + d. where a, b, c, and d are arbitrary real numbers representing transformations. Note that all outer numbers (outside the brackets) represent vertical translations, and all inner numbers represent horizontal translations. Addition and subtraction are translations, and multiplication and division are dilations. Every time a minus sign is multiplied it means it is a reflection here, 'a' stands for vertical stretch, 'b' stands for horizontal stretch, 'c' stands for horizontal movement, 'd' stands for vertical movement
We have given two functions y=b x and y = 5x + 3 which means that first, y changes into 5x i.e., vertical dilation by a scale factor of 5 and it changes to y = 5x + 3 i.e.., vertical translation of 3 units.

Answer:

Step-by-step explanation:
1 3/4 in improper form is 7/4
7 is not 9 more than 4 so its another equivalent
7/4 × 2/2 = 14/8
That isn't 9 more than the denominator either
7/4 × 3/3 = 21/12

Answer:
36 tenths
Explanation:
Well the first part to working this out is understanding that there are 10 tenths in a whole. So 3 wholes is 30 tenths.
The second part is 3 over 5 or 3/5. To write this in tenths you have to effectively double it (if you double the denominator you must double the numerator) What ever you do to the top you must do to the bottom and vice versa. So that 3 over five becomes six over ten. Add them together now you can add these fractions because they are over the same denominator (their bottom number is the same)
30 tenths plus 6 tenths equals 36 tenths.
